The Musical Instrument Digital Interface (MIDI) is a ubiquitous communications standard that enables various kinds of electronic devices to interact with each other. The range of MIDI-capable equipment includes sequencing machines, expanders, computers, and portable keyboards.
An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument, an electronic or digital derivative of keyboard instruments.[1]Broadly speaking, the term electronic keyboard or just a keyboard can refer to any type of digital or electronic keyboard instrument. These include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. However, an electronic keyboard is more specifically a synthesizer with a built-in low-wattage power amplifier and small loudspeakers.
Electronic keyboards are capable of recreating a wide range of instrument sounds (piano, Hammond organ, pipe organ, violin, etc.) and synthesizer tones with less complex sound synthesis. Electronic keyboards are usually designed for home users, beginners and other non-professional users. They typically have unweighted keys. The least expensive models do not have velocity-sensitive keys, but mid- to high-priced models do. Home keyboards typically have little, if any, digital sound editing capacity. The user typically selects from a range of preset 'voices' or sounds, which include imitations of many instruments and some electronic synthesizer sounds. Home keyboards have a much lower cost than professional synthesizers. Alesis, Casio and Yamaha are among the leading manufacturers of home keyboards.[citation needed]
Terminology[edit]
An electronic keyboard may also be called a digital keyboard, or home keyboard, the latter often refers to less advanced or inexpensive models intended for beginners. Mac cleaner pro license key. The obscure term 'portable organ' was widely used to refer electronic keyboards in the 1990s, due to the similar features between electronic keyboards and electronic home organs, the latter of which was popular in the late 20th century.
In Russia, Belarus and Ukraine, most types of electronic keyboards (including digital pianos and stage pianos) were simply often referred to as a 'synthesizer' (Russian: синтезатор, sintezator), usually with no other term to distinguish them from actual digital synthesizers.
The term electronic keyboard may also be used to refer to a synthesizer or digital piano on colloquial usage.
Components[edit]
The major components of a typical modern electronic keyboard are:
Midi Keyboard Software
- Musical keyboard: The white and black piano-style keys which the player presses, thus connecting the switches, which trigger the electronic circuits to generate sound. Most keyboards use a keyboard matrix circuit to reduce the amount of wiring necessary. Electronic keyboards often use unweighted synthesizer-style keys to save costs and reduce the weight of the instrument. In contrast, stage piano and digital pianos typically have weighted or semi-weighted keys, which replicate the feel of an acoustic piano.
- User interface system: A program (usually embedded in a computer chip) which handles user interaction with controllers such as the musical keyboard, menus, and buttons. These controllers enable the user to select different instrument sounds (e.g., piano, guitar, strings, drum kit), digital effects (reverb, echo, chorus or sustain), and other features (e.g., transposition, accompaniments, sequencer, recording, external media, etc.). The user interface system usually includes an LCD screen that gives the user information about the synthesized sound they have selected like tempo, or effects that are activated (e.g., reverb) and other features.
- Computerized musical arranger: A software program which produces rhythms and chords by the means of computerized commands, typically MIDI. Electronic hardware can also do this. Most computerized arrangers can play a selection of rhythms (e.g., rock, pop, jazz).
- Sound generator: A digital sound module, typically contained within an integrated Read-only memory (ROM), which is capable of accepting MIDI commands and producing electronic sounds. Electronic keyboards usually incorporate sample-based synthesis, but more advanced keyboards might sometimes feature physical modeling synthesis.
- Amplifier and speakers: an internal audio power amplifier, typically a few watts, connected to the sound generator chip. The amplifier is then connected to small, low-powered speakers that reproduce the synthesized sounds so that the listener can hear them. Less expensive instruments may have a single mono speaker. More expensive models may have two speakers producing stereo sound.
- Power supply: Keyboards may or may not have an internal power supply system built to the main circuit board, but most modern keyboards are often equipped with an included AC adapter.
- MIDI terminals: Most keyboards usually incorporate 5-pin MIDI connections for data communication, typically so the keyboard can be connected with either a computer or another electronic musical instrument, such as a synthesizer, a drum machine or a sound module, allowing it to be used as a MIDI controller. Not all keyboards have conventional MIDI terminals and connector. The least expensive models may have no MIDI connections. Post-2000s keyboards may have a USB instead, which serve as both input and output in a single connection. In the 2010s, conventional MIDI in/out terminals are only available in professional-grade keyboards, stage pianos and high-end synthesizers, while low-cost home keyboards, digital pianos, and budget synthesizers use USB as the only connection available.
- Flash memory: Some electronic keyboards have a small amount of onboard memory for storing MIDI data and/or recorded songs.
- External storage device: Usually available on professional-grade keyboards and synthesizers, this allows the user to store data in externally connected storage media such as ROM cartridges, floppy disks, memory cards and USB flash drives. Floppy disks and cartridges were obsolete by the early 2000s, with memory cards starting to replace them shortly afterwards. USB storage was originally less common at the time, but was later popularized by Yamaha's lineup of workstation keyboards in 2005 and has become a standard feature ever since. Most keyboards in the 2010s uses USB storage, with the exception of some Casio and Korg models.
- Music stand: A metal or plastic rack for holding sheet music or music books upright. The music stand is usually removable to facilitate storage and transportation.
- Sustain jack: If a home keyboard has a sustain feature, replicating the device used on acoustic pianos, only a 1/4' jack is provided. The musician must buy a separate sustain pedal and plug it in. By comparison, on a digital piano, a sustain pedal is often built into the frame. The least expensive home keyboards do not have a sustain function or a sustain pedal jack, which limits their use to early beginners.

History[edit]
Classifications[edit]
Conventional home keyboards differ from other electronic keyboards due to the design, features and target market:
- Digital piano - Electronic keyboards designed to sound and feel like an ordinary acoustic piano. They typically contain an amplifier and loudspeakers built into the instrument. In most cases they can fully replace acoustic pianos and provide several features, such as recording and saving files to a computer. Many digital pianos can imitate the sounds of several instruments, including a grand piano, electric piano, pipe organ, Hammond organ and harpsichord. They are not sensitive to the climate or humidity changes in a room and there is also no need for tuning, as with acoustic pianos. Digital pianos are often mounted on stands with a fixed sustain (or other) pedal attached to the frame; as such, most are not designed for transportation. The target market is mid-level to advanced pianists.
- Stage piano - A type of high-quality digital piano with weighted keys, designed for professional touring use on stage or in a recording studio. The Hammond organ and electric piano sounds on a stage piano are typically more realistic than those found on a digital piano.
- Synthesizer - Electronic keyboards that use various sound synthesis technologies to produce a wide variety of electronic sounds.
- Workstation - Professional electronic keyboards that combine the features of a synthesizer and a conventional home keyboard. Workstations have a range of high-quality sampled instrument sounds, as well as extensive editing/recording capability, computer connectivity, high-powered speakers, and often include external memory storage for storing customized data, MIDI sequences, and even additional instrument samples. A high-end workstation keyboard may include several features similar to a digital audio workstation computer software, allowing an even more advanced features such as mixing, mastering, sound design, creating loops and patterns, composing electronic music, etc.
- MIDI controller - An electronic keyboard that does not produce a sound of its own. It is used to trigger sounds from a sound module or software synthesizer by means of MIDI cable and connections. MIDI controllers often provide other sliders, knobs and buttons, which enable the player to control elements such as volume.
- Keytar - A small synthesizer that resembles a guitar which can be played in similar position as an electric guitar: worn on a strap over the shoulders, enabling the performer to move around on a stage. The name is a portmanteau of keyboard and guitar.
Compared to digital pianos or stage pianos, digital home keyboards are usually much lower in cost, as they have unweighted keys. Like digital pianos, they usually feature on-board amplifiers and loudspeakers. Stage pianos, however, typically do not have integrated amplifiers and speakers, as these instruments are normally plugged into a keyboard amplifier in a professional concert setting. Unlike synthesizers, the primary focus of home electronic keyboards is not on detailed control or creation of sound synthesis parameters. Most home electronic keyboards offer little or no control or editing of the sounds (although a selection of 128 or more preset sounds is typically provided).
Concepts and definitions[edit]
- Auto accompaniment / chord recognition: Auto accompaniment is used on programmed styles to trigger specific chords that will sound when a single key is pressed on the keyboard. For example, when the auto accompaniment feature is on, and the performer presses a 'C' note in the low range of the keyboard, the auto accompaniment feature will play a C Major chord. In many keyboards, the auto accompaniment feature will play the automatic chords in a rhythm and style that is appropriate for the musical style (e.g., rock, pop, hip-hop) selected by the performer (see the Accompaniment backing track section for more). When the on-board rhythm track is turned on, the auto-chords will be played automatically in the tempo of the rhythm track. Many keyboards have an option to form on-bass chords, as well as many other complex chords.
- Demonstration: Most keyboards have pre-programmed demo songs. As the name 'demo' implies, one usage of these pre-programmed songs is for a salesperson to use to demonstrate the capabilities of the keyboard, in terms of its different voices and effects. The demo songs can also be used for entertainment and learning. Some keyboards have a teaching feature that will indicate the notes to be played on the display and wait for the player to press the right one.
- Velocity sensitivity (also found under the keyword touch sensitivity in some manuals): While the least expensive keyboards are simply 'on-off' switches, mid-range and higher-range instruments simulate the process of sound generation in chordophones (string instruments) which are sensitive to the speed (or 'hardness') of a key press. Mid-range instruments may only have two or three levels of sensitivity (e.g., soft-medium-loud). More expensive models may have a broader range of sensitivity. For implementation, two sensors are installed for each key: the first sensor detects when a key is beginning to be pressed and the other triggers when the key is pressed completely. On some higher-end electronic keyboards or digital pianos, a third sensor is installed. This third sensor allows the player to strike a key and still sound a note even when the key has not yet come to its full resting position, allowing for faster (and more accurate) playing of repeated notes. The time between the two (or three) signals allows a keyboard to determine the velocity with which the key was struck. As the key weight is constant this velocity can be considered as the strength of the press. Based on this value the sound generator produces a correspondingly loud or soft sound. The least sophisticated types of touch sensitivity cause the keyboard to change the volume of the instrument voice. The most sophisticated, expensive types will trigger both a change in volume and a change in timbre, which simulates the way that very hard strikes of a piano or electric piano cause a difference in tone—as well as an increase in volume. Some sophisticated touch-sensitivity systems accomplish this by having several samples of an acoustic instrument note per key (e.g., a soft strike, a mid-level strike, and a hard strike). Alternatively, a similar effect can be accomplished using synthesis-modelling of the ADSR envelope or digital modelling (e.g., for the hard strike, the keyboard would add the timbres associated with a hard strike—in the case of a Fender Rhodes voice, this would be a biting, 'bark' sound).
- After-touch: A feature brought in the late 1980s (although synthesizers like the CS-80 extensively used by artists like Vangelis featured after-touch as early as 1977) whereby dynamics are added after the key is hit, allowing the sound to be modulated in some way (such as fade away or return), based upon the amount of pressure applied to the keyboard. For example, in some synth voices, if the key continues to be pressed hard after the initial note has been sounded, the keyboard will add an effect such as vibrato or sustain. After-touch is found on many mid-range and high-range synthesizers, and is an important modulation source on modern keyboards. After-touch is most prevalent in music of the mid to late 1980s, such as the opening string-pad on Cock Robin'sWhen Your Heart Is Weak, which is only possible with the use of after-touch (or one hand on the volume control). After-touch is not normally found on inexpensive, beginner-level home keyboards.
- Polyphony: In digital music terminology, polyphony refers to the maximum number of notes that can be produced by the sound generator at once. Polyphony allows significantly smoother and more natural transitions between notes. Inexpensive toy electronic keyboards designed for children can usually only play five to ten notes at a time. Many low priced keyboards can perform 24 or 32 notes at a time. More advanced keyboards can perform over 48 notes at a time with 64 or 128 notes being common. Digital pianos, has more complex polyphonic system and could perform by up to 256 notes.
- Multi-timbre: The ability to play more than one kind of instrument sound at the same time, such as with the Roland MT-32's ability to play up to eight different instruments at once.
- Split point: The point on a keyboard where the choice of instrument can be split to allow two instruments to be played at once. In the late 1980s it was common to use a MIDI controller to control more than one keyboard from a single device. The MIDI controller had no sound of its own, but was designed for the sole purpose of allowing access to more sound controls for performance purposes. MIDI controllers allowed one to split the keyboard into two or more sections and assign each section to a MIDI channel, to send note data to an external keyboard. Many consumer keyboards offer at least one split to separate bass or auto-accompaniment chording instruments from the melody instrument.
- Minikeys: Most electronic keyboards have keys that are similar to the size of keys on an acoustic piano. Some electronic keyboards have minikeys, either because they are targeted at child users or to make the instrument smaller and more portable.
- Accompaniment backing tracks: Pre-programmed musical accompaniment tracks (also called rhythm pattern or rhythm style by some manufacturers), consist of a variety of genres for the player to use (e.g., pop, rock, jazz, country, reggae). The keyboard plays a chord voicing and rhythm which is appropriate for the selected genre. In general, programmed backing tracks usually imitate the sound of a rhythm section or an ensemble. Certain keyboards may include a feature that allows the performer to create, compose and customize their own accompaniments. This feature is usually called a pattern sequencer, rhythm composer, or a style creator.
- In addition to the basic accompaniment tracks, some keyboards have an extra feature to play different loops in conjunction with the backing track itself.
- Accompaniment sections and synchronization: Usually, backing tracks comprises two to four sections, as well as fill-in patterns, introduction/ending patterns, and various synchronizations to improve the effects of the accompaniment.
- Tempo: A parameter that determines the speed of rhythms, chords and other auto-generated content on electronic keyboards. The unit of this parameter is beats per minute. Many keyboards feature audio or visual metronomes (using graphics on a portion of the display) to help players keep time.
- Auto harmonization: A feature of some keyboards that automatically adds secondary tones to a note based upon chords given by the accompaniment system, to make harmony easier for players who lack the ability to make complex chord changes with their left hand.
- Wheels and knobs: Used to add effects to a sound that are not present by default, such as vibrato, panning, tremolo, pitch bending, and so on. A common wheel on contemporary keyboards is the pitch bend, adjusting the pitch of a note usually in the range of ±1 tone. The pitch bend wheel is usually on the left of the keyboard and is a spring-loaded potentiometer.
- Drawbars: Usually found only on high-end, expensive keyboards and workstations, this feature allows the performer to emulate digitally-modeled sounds of a tonewheel electronic organ (hence drawbar). It consists of nine editable virtual sliders that resemble the drawbars of a tonewheel organ, and features various effects such as rotary speaker, percussion, and tremolo. The setting can be saved to the keyboard's user memory or storage device.
- Piano simulation: A common feature of the digital piano, stage piano, and high-end workstations that allows real-time simulation of a sampled piano sound. It provides various piano-related effects, such as room reverberation, sympathetic resonance, piano lid position (as on a grand piano), and settings to adjust the tuning and overall sound quality.
- Keyboard action describes the mechanism and feel of the keyboard. Keyboards can be roughly divided into non-weighted and weighted.
- Non-weighted keyboards has a light, springy feel to their keys, similar to the action of an organ. The least expensive keyboards, often with non-fullsize keys, uses keys that are mounted on soft rubber pads that also acts as electronic switches. Most electronic keyboards use spring-loaded keys that make some kinds of playing techniques, such as backhanded sweeps, impossible, but make the keyboards lighter and easier to transport. Players accustomed to acoustic piano keys may find non-weighted spring-action keyboards uncomfortable and difficult to play effectively. Conversely, keyboard players accustomed to the non-weighted action may encounter difficulty and discomfort playing on an acoustic piano.
- Weighted keyboards indicate that some kind of effort has been made to give the keyboard more resistance and responsive feel similar to that of an acoustic piano.
- Semi-weighted keys is a term applied to keyboards with spring action like a non-weighted keyboard but that have extra weight added to the keys to give them more resistance and responsive feel.
- Hammer action keys uses some kind of mechanism to replicate the action of a mechanical piano. This is often achieved with some kind of lever mechanism connected to the key.
- Graded hammer action keys does what hammer action keys do, but also has a different feel on the low versus high notes as on a mechanical piano keyboard. The lower note keys have a higher resistance than the higher note keys.[2][3]
MIDI controls[edit]
MIDI, Musical Instrument Digital Interface, is a serial data connection which operates with any make or model of instrument which provides for it.
Electronic keyboards typically use MIDI signals to send and receive data, a standard format now universally used across most digital electronic musical instruments. On the simplest example of an electronic keyboard, MIDI messages would be sent when a note is pressed on the keyboard, and would determine which note is pressed and for how long. Additionally, most electronic keyboards now have a 'touch sensitivity', or 'touch response' function which operates by an extra sensor in each key, which estimates the pressure of each note being pressed by the difference in time between when the key begins to be pressed and when it is pressed completely. The values calculated by these sensors are then converted into MIDI data which gives a velocity value for each note, which is usually directly proportional to amplitude of the note when played.
MIDI data can also be used to add digital effects to the sounds played, such as reverb, chorus, delay and tremolo. These effects are usually mapped to three of the 127 MIDI controls within the keyboard's infrastructure – one for reverb, one for chorus and one for other effects – and are generally configurable through the keyboard's graphical interface. Additionally, many keyboards have 'auto-harmony' effects which will complement each note played with one or more notes of higher or lower pitch, to create an interval or chord.
DSP effects can also be controlled on the fly by physical controllers. Electronic keyboards often have two wheels on the left hand side, generally known as a pitch bend and a modulation wheel. The difference between these is that the pitch bend wheel always flicks back to its default position – the center – while the modulation wheel can be placed freely. By default, the pitch bend wheel controls the pitch of the note in small values, allowing the simulation of slides and other techniques which control the pitch more subtly. The modulation wheel is usually set to control a tremolo effect by default. However, on most electronic keyboards, the user will be able to map any MIDI control to these wheels. Professional MIDI controller keyboards often also have an array of knobs and sliders to modulate various MIDI controls, which are often used to control DSP effects.
Most electronic keyboards also have a socket at the back, into which a foot switch can be plugged. The most common function is to simulate the sustain on a piano by turning on and off the MIDI control which adds sustain to a note. However, since they are also simple MIDI devices, foot switches can usually be configured to turn on and off any MIDI controlled function, such as switching one of the DSP effects, or the auto-harmony.[citation needed]
Keyboard ensemble[edit]
In live performances, multiple electronic keyboards could be played together at one time, each by one musician, forming a keyboard ensemble. Keyboard ensembles are mostly performed within a band on an elaborate stage, while some can even serve as a simpler substitute to the more conventional orchestra, replacing stringed and wind instruments.

A MIDI keyboard or controller keyboard is typically a piano-style electronic musical keyboard, often with other buttons, wheels and sliders, used for sending MIDI signals or commands over a USB or MIDI 5-pin cable to other musical devices or computers. MIDI keyboards lacking an onboard sound module cannot produce sounds themselves, however some models of MIDI keyboards contain both a MIDI controller and sound module, allowing them to operate independently. When used as a MIDI controller, MIDI information on keys or buttons the performer has pressed is sent to a receiving device capable of creating sound through modeling synthesis, sample playback, or an analog hardware instrument. The receiving device could be:
- a computer running a digital audio workstation (DAW) or a standalone VST/AU instrument (alternatively, the computer could be used to re-route the MIDI signal to other devices)
- a sound module
- a digital (digital piano/stage piano) or analogue (synthesizer) hardware instrument with MIDI capability, such as a drum machine
While many digital and analog hardware keyboards in the aforementioned categories of digital piano, stage piano, and synthesizer can be used as MIDI controllers if they have MIDI capability, they often do not offer the same level of software integration and number of MIDI-mappable controls as a dedicated MIDI keyboard. MIDI keyboards are often utilized by individuals who work with DAWs and software instruments, from hobbyists to professional musicians working in recording studios or concert stages.
Signal flow: MIDI keyboard to audio[edit]
Below is an example of possible signal chains for a MIDI keyboard setup, with the goal of producing audio:
MIDI Keyboard → 5-pin MIDI connector OR USB cable (will need a 'B' connector, so 'USB A to B' or 'USB C to B', depending on computer) → computer running a DAW or a standalone VST/AU instrument OR a sound moduleOR a digital piano, stage piano, or synthesizer with MIDI capability → audio sound device (amplifier and speakers or headphones)
Class compliance and power source[edit]
When using a MIDI keyboard with a computer, class compliance must be taken into consideration. Audio editing software download full version. Class compliant means, essentially, 'plug and play': upon being plugged in (USB or 5-pin) and powered up, MIDI keyboards that are class compliant should be recognized by any computer. https://gyazsb.over-blog.com/2021/01/smart-utility-3-2-55.html. MIDI keyboards and MIDI-capable hardware keyboards that are not class compliant require a keyboard-specific software driver to be installed on the computer in order for the keyboard to be recognized.
While most MIDI keyboards produced in the 2010s are bus-powered, meaning their electrical power is supplied through the same USB connection that transfers MIDI data to the computer, some keyboards have the option of, or even require, using external power to operate. If using a traditional 5-pin MIDI connector instead of USB, the MIDI keyboard will likely require external power, as 5-pin MIDI connections cannot send the current needed to power a keyboard. If using a MIDI-capable hardware keyboard as a controller, one will also likely need external power, as most 2010s hardware keyboards rely on external power to function.
Keyboard action[edit]
The action of a keyboard is the internal mechanism by which the keys work in order to move and produce sound, or, in this case, MIDI data. Two major types of keyboard actions exist: those derived from traditional, European, key-based instruments and non-traditional, contemporary designs that allow for expanded playing possibilities.
Traditional[edit]
MIDI controllers in this category have keys meant to resemble those of a grand piano, pipe organ, or synthesizer. Each of these action types is designed differently from the next, which, in turn, gives the action a particular 'feel' to the player and lends it to an ideal usage.
- Synth action: un-weighted, often spring-loaded— ideal for playing quickly and may be favored by those with no piano or keyboard experience due to less required effort to depress the keys
- Semi-weighted action: similar to synth action, but with slightly increased resistance— also ideal for playing quickly, but allows for more dynamic playing on velocity-sensitive sound patches due to increased feedback from the keys
- Waterfall keys: semi-weighted keys with smoothed and rounded edges— meant for emulating organ keys (i.e. Hammond B-3 organ) and ideal for playing organ-specific techniques (i.e. palm glissando/smears)
- Hammer action: piano-style action with fully weighted keys— meant to provide resistance similar to an acoustic piano action and ideal for playing piano or electric piano instrument patches
- Graded hammer action: hammer action with graded resistance— keys in the upper register are lighter than keys in the lower register, and resistance increases incrementally as one descends the keyboard from high to low, like an acoustic piano action (e.g. grand piano)
- Graded hammer action with wood: graded hammer action with wooden key cores— the closest in realism to an acoustic piano action (as acoustic piano keys are made of wood)
Many examples of the above actions, other than the waterfall keys, will include a small lip that protrudes from the top of the distal end of the white keys. This is emulating a customary design detail found on acoustic piano keys. Keyboards with any type of hammer action are most likely to display this lip.
Sensor type[edit]
Most of these traditional key keyboards determine the attack velocity, sustain, and release of a note based on a calculation made between two sensors in each key. Some high-end keyboards now feature triple sensors, claiming improved accuracy in the tracking of key movement, which could translate into a more detailed, and perhaps more expressive, performance. Pokemon com playtcgo.
Aftertouch[edit]
Some MIDI keyboards are capable of sending aftertouch data, which can be assigned to a variety of effects, including: vibrato, pitch bends, and volume swells. Aftertouch data is generated when a key is depressed further into the keybed after its initial depression (without releasing the key). Keyboards can be equipped with channel or polyphonic aftertouch. The former sends only one aftertouch message, regardless of which key is depressed; the latter sends individual aftertouch messages for each key. Keyboards with every key aftertouch can enable the performer to create aftertouch effects on particular notes, such as emphasizing a melody note by continuing to press it.
Non-traditional[edit]
Not all MIDI keyboards utilize variations on the traditional piano-style action. One example of a MIDI keyboard with a non-traditional action is the Continuum Fingerboard, which is based on a 'fretless' type keyboard interface, enabling portamento style note changes at will during play. Another unconventional MIDI keyboard is the Tonal Plexus keyboard, which provides for up to 1266 different pitches possible through the TPX6 1266 Keys (Microtonal MIDI Controller).

The Roli Seaboard line of MIDI keyboards has soft, squishy keys. All the above-mentioned MIDI keyboards take the concept of aftertouch to new heights: for instance, the Roli Seaboards can sense left-to-right, front-to-back, downward pressure/depth, and the rate of change in each of these parameters. All that information can then be used to control the behavior of a digital instrument.
Size and number of keys[edit]
MIDI keyboards come in a wide range of sizes and number of keys, each with their own benefits and drawbacks. Generally speaking, some sizes are more common while others are less common, both in online stores and in bricks and mortar music stores. Logic buy album.
Common[edit]
- 25-key: generally the smallest MIDI keyboard available— portable and light, but only suitable for playing one-handed piano parts such as basslines
- 49-key: considered the smallest MIDI keyboard size upon which to play two-handed piano parts effectively
- 61-key: ideal size for playing two-handed piano parts— same key count as a single manual from a classic organ like the Hammond B-3
- 88-key: full key range— same key count as an acoustic piano— the gold standard when playing piano and electric piano, but least portable and heaviest of the MIDI keyboards
Uncommon[edit]
- 32 & 37-key: compared to 49-key keyboards, these are more compact and easy to carry. Compared with a 25-key keyboard, they offer a greater range
- 73 & 76-key: compared to 88-key keyboards, these are more compact and easy to carry. Compared with a 61-key keyboard, they offer a greater range
Most 25-key through 49-key keyboards come equipped with synth or semi-weighted actions. Most 49-key and 61-key keyboards come equipped with semi-weighted actions, but some may be found with hammer actions. Waterfall keys can be found occasionally on some 61-key and 73-key keyboards. Most 73-key through 88-key keyboards come equipped with hammer actions; however, some may be outfitted with semi-weighted actions.
Key size[edit]
MIDI keyboards are usually full-size keys, like a grand piano. Some smaller keyboards use minikeys, which are smaller. Some tiny keyboards have flat minikeys which are even smaller.
Controls (buttons, knobs, faders, wheels)[edit]
Electric Keyboard With Midi Driver
Many MIDI keyboards include control devices (other than the keys), which may allow for manipulation of DAW controls and/or the sound generator (either software or hardware). Provided they are mapped, or mappable, to the correct function, these allow the player to access a DAW or alter the sound of an instrument patch without taking hands off the keyboard.
- Buttons: may be assignable or allow for editing of menus, settings, MIDI CC information, splits, use of DAW transport controls, transpose function, or octave up/down
- Knobs: either potentiometers or endless encoders— typically assignable to a function
- Sliders/faders: typically assignable— common assignments are as drawbars for an organ, to control channel faders, or to control equalizer (EQ)
- Pitch bend and modulation: allows for control of pitch bending and modulation via one of several control setups.
- Traditional two wheels: spring-loaded pitch bend wheel and a modulation wheel
- X/Y joytick: capable of rotation in a full circle— pitch bend and modulation are mapped out on an X/Y plot
- Roland-style pitch/modulation: spring-loaded, three-directional lever— left-to-right for pitch bend and up for modulation
- Nord pitch stick & modulation: tensioned wooden stick that moves left-to-right for pitch bend— traditional modulation wheel (made of ceramic)
- Touch strips: touch-sensitive strips assignable to several functions— less common on most keyboards
- Pads: velocity-sensitive, rubberized pads— can be assigned to trigger events from drum hits to patch changes
- Breath controller: A device which involves a mouthpiece which is gripped by the teeth or held in front of the mouth with a holder; by blowing into it, the user can control synth tones. It can be used to give a vocal, singing quality to notes played on a keyboard
- Screens: depending on make and model, some keyboards have no touchscreen, such as with 1980s LCD screen— others have touch screens that intuitively interface with companion software
- Software integration: A MIDI keyboard offers an automatic configuration option to integrate with a DAW.[1]
Foot controllers[edit]
MIDI keyboards often have the ability to accept foot controllers, of which there are four main types: piano pedals, expression pedals, stomp boxes, and organ-style foot pedal keyboards.
- Piano pedals: can be a single sustain pedal (two types) or up to a full grand piano-style triple pedal, with sostenuto and una corda pedals, like an acoustic piano
- Sustain pedals: Momentary sustain pedals only send a message when the pedal is on or off. Continuous sustain pedals send a real-time MIDI value of the sustain pedal's position, allowing for realistic tracking of the pedal's movement (provided the controller and sound source support continuous sustain).
- Expression pedals: send a continuous MIDI value that can be mapped to control parameters like volume (a 'swell pedal'), effects (chorus, reverb, etc.), and patch changes
- MIDI stomp boxes: similar in form to a guitar pedal board, but are configurable to send MIDI commands for various actions (i.e. patch changes, looping, or playing chords)
- Organ foot pedal keyboards: traditional organ pedal keyboards for those used to playing Hammond B3's or church organs. While they are intended to send MIDI values for organ bass notes, if they are hooked up to a DAW, the pedals can trigger chords or play a high-pitched melody.
